Despite a few unexpected bumps and curves in their explorations at Gusev Crater and Meridiani Planum, the Mars Exploration Rovers have been working away and both Spirit and Opportunity have put in a very productive month's worth of work on the Red Planet.

I got an email last night from Anne Verbiscer, whom I had contacted about rounding up some amateur astronomers to help the Cassini mission with some photometric observations of Hyperion.

There were a few talks at the Division of Planetary Sciences meeting dealing with a rare and fortuitous event that happened on January 13, 2005.

According to Jason Perry, the much-anticipated Titan-7 RADAR imagery across Titan's southern hemisphere may have been lost due to an error on Cassini's solid state recorder. That will be very sad if it turns out to be true.

Today is the last day of DPS, and the first that has not had a press conference session at lunchtime, so I have a few moments here to do some catching up.

This lovely animation of Itokawa represents 20 individual images taken between 18:10 on September 5 and 00:30 on September 6, from a distance of less than 700 kilometers away.

Spirit has returned enough pictures from the summit of Husband Hill for the Mars Exploration Team to have put together a 240-degree color panorama of her view, which they released at a news conference today, held at NASA headquarters in Washington D.C. In coming days, the rover will return the rest of the images to complete the full, 360-degree, color panorama.

On August 2, 2005, MESSENGER flew by Earth at an altitude of a mere 2,347 kilometers above Mongolia.

Hayabusa (formerly known as MUSES-C) is getting very, very close to its target asteroid Itokawa, and should be arriving soon!

I had very much hoped to be able to post an update about the Deep Impact mission this week, but it looks like my various sources are keeping very very quiet (or maybe they are just tired of me pestering them :)

First, here's a nice shot of Epimetheus, which was taken about a month ago.

Checking the Cassini raw images website, I found quite a few more images of Hyperion this morning. It looks like Cassini had a leisurely flyby of the little moon from roughly 700,000 kilometers' distance.

The Space Shuttle couldn't land at Kennedy Space Center today because of concerns about weather, so I have been expecting a launch delay to be announced for Mars Reconnaissance Orbiter. Indeed, a 24-hour delay has just been announced; the new launch date is Thursday, August 11 from 7:50 to 9:35 a.m. EDT (11:50 to 13:35 UTC).

I was browsing the MESSENGER website just now, and found a neat photo. It's a picture of MESSENGER as seen from Earth when it flew by yesterday.

MESSENGER is now returning images as it is bearing down on Earth.

Cassini mission planner Dave Seal just gave me the latest reference trajectory for Cassini, so I've gone through and updated the flyby altitudes on the Cassini tour page.

It's official: Enceladus has joined the rarefied community of Solar System objects that have been caught in the act of making new geology.

We haven't forgotten about Deep Impact, but there's still no word on the crater size.
